A drive torque distribution controller for a four-wheel drive vehicle, a method of controlling a four-wheel drive vehicle and computer program product

摘要

A control device 20 for controlling a drive torque distribution to a front wheel 9 and a rear wheel 10 includes a receiving section 21 for obtaining lateral acceleration of the vehicle, engine output torque and turning radius of the vehicle during cornering of a vehicle 1 a determination section 22 for determining a rear wheel drive torque distribution rate which is a rate of torque to be transmitted to the rear wheel relative to the drive torque corresponding to the engine output torque based on the obtained lateral acceleration of the vehicle, the engine output torque and the turning radius of the vehicle and a control signal outputting section 23 for outputting a control signal to a driving-torque transmitting device 13 so as to set the driving torque transmitted to the rear wheel such that the A drive torque to be distributed to the rear wheel is controlled in accordance with the determined rear wheel drive torque distribution rate.
